     <dcterms:abstract xml:lang="fr">Une augmentation de la prévalence des évènements thrombotiques a été observée chez les patients atteints de COVID 19 dès le début de la pandémie. En ce sens, de nombreuses études et recommandations ont été précocement mis en place afin de prendre en charge ces complications, sans données initiales sur les complications thrombohémorragiques. Le travail présenté ici va s’articuler autour de l’étude rétrospective Coviclot et plus particulièrement autour d’une cohorte du CHU de Rennes. L’objectif était de mettre en évidence des caractéristiques de ces patients à risque et d’évaluer les effets des nouveaux protocoles de thromboprophylaxie mis en place dans ce contexte, tout en confrontant ces résultats aux connaissances actuelles. L’étude des cohortes a montré que les facteurs de risques de complications thrombotiques étaient la gravité de la pneumopathie, l’hypoxémie sévère, ainsi que l'inflammation et l'hypercoagulabilité. Une thromboprophylaxie renforcée était associée à une diminution des complications thrombotiques (HR 0.81; 95% CI, 0.66-0.99) sans majoration du risque hémorragique (HR, 1.11; 95% CI, 0.70-1.75). Ce travail a montré le caractère bénéfique d’un traitement thromboprophylactique renforcé en diminuant l’incidence des complications thrombotiques, sans pour autant majorer la survenue de complications hémorragiques ou influer la mortalité chez les patients pris en charge en réanimation</dcterms:abstract>
     <dcterms:abstract xml:lang="en">A raise of the prevalence of thrombotic events has been observed on patients suffering from COVID-19 from the beginning of the pandemic. Consequently, numerous studies and recommendations were initially set up with the objective to handle those complications, without base data on thrombo-hemorrhagic complications. The work presented here will be based on the COVICLOT retrospective study, and more particularly on a study led on a group of patients from the UHC (University Hospital Center) of Rennes. The aim was to highlight common characteristics between different high risk patients and evaluate the effects of new thromboprophylaxis protocols created in this context while comparing results with previous knowledges. The cohort study showed that the risk factors for thrombotic complications were the severity of the pneumonia, severe hypoxemia, as well as inflammation and hypercoagulability. Reinforced thromboprophylaxis was associated with a decrease in thrombotic complications (HR 0.81; 95% CI, 0.66-0.99) without an increased risk of bleeding (HR, 1.11; 95% CI, 0.70-1,75). This work has shown the beneficial nature of thromboprophylaxis strengthened by decreasing the incidence of thrombotic complications without increase the occurrence of bleeding complications or affect mortality in patients cared in intensive care</dcterms:abstract>
